Window construction



May 2, 1939. E. WANDSCHEER WINDOW CONSTRUCTION Filed April 3, 1937 IN V EN TOR. M u/ llllll'lllllll llll'l' II I ATTORNEY Patented May 2, 1939 UNlTD T'ES ATENT ()FFlCE My invention relates to a type of window construction.

An object of my invention is to provide a window construction which does not require the need of putty for fastening the window glass within the framework.

A further object of my invention is to provide a window construction which includes means for retaining the window panes in a simple and convenient manner.

A further object of my invention is to provide such a construction which allows insertion of the window glass from the top thereof and which construction allows the engagement of said window glass-which can be inserted as a single unit.

A further object of my invention is to provide a junction between two or more panes of glass which includes features which prevent an accumulation of moisture within the window itself.

A further object of my invention is to provide the above characteristics in a construction which is simple and easy to manufacture.

With these and other objects in view, my'invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which:

Figure 11 is an end view of Figure 10 and Figure 12 is a sectional view taken along the lines 'l2|2 of Figure 8.

My invention contemplates the construction of a window which can be easily assembled and which will satisfy all the ordinary requirements of weather resistance and the like without the necessity of using puttied joints.

I have used the character! todesignate the side members of the window frame, with the lower member being indicated by the character II. A center member I3 is provided, having the inwardly projecting grooves M. The upper member I5 is suitably mortised at I6 to the side mem- 5 bers l0 and the side members Ill include the vertical grooves l1. Further, lower grooves l8 are provided to receive the bottom edges of the windows. The window panes are made up in pairs having the glass windows IS. The windows 10 [9 are firmly retained in joined relation by means of the metal members 20. The metal members 20 are formed of an integral strip of thin resilient metal and include the inwardly bowed portions 2| which continue into the hollow channeled por- 15 tions 22 into which channeled portions the glass members [9 are received. The channeled portions 22 merge into inner flanges 23 which terminate at a higher point or outwardly at a greater distance from the bent portions 2 I. After 20 the panes l9 are suitably joined by means of the metal members they will then be ready for insertion into the corresponding grooves. The double pane structure is then inserted in' the grooves l I and forced downwardly until the lower edges engage the grooves l8. Next the retaining members 24 are employed to hold the upper parts of the windows. The members 24 include the tongues 25 which extend at the sides thereof and which engage within the grooves ll. 30

It will be noted that the tongues 25 are recessed at 26 (see Figure 4) and a wood screw 21 is normally held by means of the member 24 and at the approximate midpoint thereof. The screw 21 is loosened and the tongues 25 are then inserted in the grooves and the members 24 are forced downwardly so that the upper edge of the window is received within the recess 26. The screw 21 is then screwed into the framework [5 and the window panes are then retained securely along the perimeters thereof. The metal mem-' bers 20 extend directly adjacent to the side members l0 and it will be noted that the pan-es I9 extend beyond the border of the same so that they can be incorporated within the grooves. 45 The metal members 20 are not continued until the maximum width of the panes to prevent the accumulation of moisture which would be present atsuch joints if the member extended to the maximum width between the grooves. 50

As shown in Figure 2, the view shows the inside of the window frame with the opposite side being exposed outside of the building or toward the weather conditions or other elements.- The metal members 20 insure that no moisture will enter '5= through the joints by virtue of the following: moisture, in dripping down the outer surfaces 28 (see Figure 7) will first contact the upper looped portion 2|. Such moisture will then flow downwardly into the channel 22 and will rise in the channel until it is level with the loop 2| when it will then flow over the loop and the surface 20. The feature of making the inner flanges 23 higher than the loop 2| then insures that the moisture will not pass inwardly inside of the glass. The moisture passes down along the surface and then from the loop portion 2].

The snug engagement of all of the members then makes for a composite structure which is securely held in place and which eliminates the need for application of putty or similar substances at any place. Although the drawing shows the member 20 slightly spaced from the inner frames Ii] and I3, it will be understood that the metal edges are positioned so that they actually contact the same, this feature being shown slightly exaggerated for clarification. The strip v20 can be quickly removed at any time and the entire glass arrangement withdrawn for replacements, etc., and the joining feature allows for small size panes to be grouped forming a correspondingly larger complete window, the advantages of which are readily apparent.

A further modification is shown in Figure 8 wherein all of the other features are present with the exception, however, that side grooves 29 are located in the side and center strips 30 which are bounded on both side rails by further members 3|, 32, and 33. In this construction, the grooves are located centrally of the frame and the retaining member 34 extends into the further tongue 35. The retaining members 34 are indented at 36 centrally along the bottom of the member 34, forming a channel to receive the top of the window as shown in Figure 12. In this construction the upper edges of the panes are retained by means of the members 34 which are inserted within the grooves 29, the tongues entering such grooves. The screws 21 are first removed and then inserted through the opening 31. Lower grooves 38 receive the lower edges of the glass and in this manner it will again be seen that the entire structure is moisture proof and provides a composite rigid structure without the necessity of using putty.

It will be understood that the entire window sash arrangement can be made of metal if such is desired. It will also be further understood that if necessary more than two panes of glass can be attached in a Vertical arrangement, or in other words if necessary three or four panes can be arranged one above the other with the strips 20 between the adjoining pairs. Also any grouping can be used in horizontal or side by side relation.

It will be seen that I have provided a window construction which includes means for grouping the panes, which includes means for incorporating the glass of such windows within the framework without the necessity of using putty or other such medium, which includes a weather proof arrangement, and which is easily assembled and constructed and which can be manufactured at a reasonable cost.

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified form of structure or use of mechanical equivalents, which may be reasonably included within their scope.
